Abstract

This invention relates to a method of and device for measuring an extremely small quantity of oxygen in gas depending on the intensity of light generated when yellow phosphor vapor is reacted with oxygen in the sample gas. Together with the sample gas, a fixed quantity of oxygen is continously fed to the reaction chamber and reacted with yellow phosphor vapor so that the intensity of light generated by said reaction is measured. Density of oxygen in gas is found from the difference between a value of measured intensity of light and that of the intensity of light generated on reaction of yellow phosphor vapor with added oxygen, or from the difference between oxygen density obtained from the measured value and that of added oxygen. Addition of a fixed quantity of oxygen is performed in such process that pre-conditioned oxygen-containing gas is fed together with a fixed quantity of sample gas, or oxygen in the atmosphere is adapted to permeate an oxygen permeable film provided in the sample gas feeding system or in the yellow phosphor vapor feeding system. An extremely small quantity of oxygen under several ppb in the sample gas can continously be measured at high precision.
